Rewrite the code above so that the variable is substituted for the value 150 and the motors are spinning in the opposite directions. b) Create a second variable motorSpeed2. Using motorSpeed and motorSpeed2, modify the code so that the motor B spinning at twice the speed of motor A in the same direction.

C Programming Language (Code With C Programming Language) Problem Title : Visible Trees There is a legend about a magical park with N × N trees. The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees. On the second column, Bunga can see…

How is the body of a for loop defined? A. The body of a for loop is defined by an indented block of code following the for statement, similar to the body of an if statement. B. The body of a for loop is defined by an opening curly brace, one or more lines of code and a closing curly brace. C. The body of a for loop is defined by a left parenthesis, one or more lines of code and a right parenthesis. D. For loops do not have a body. What is a for loop? A. The for loop is the new improved three loop as it was defined in Python version 2. B. The for loop enables a program to repeat a block of code multiple times. C. The for loop enables a program to repeat a block of code one time, much like the if statement. D. The for loop is a block of code included at the beginning (the for) of a program. Which of the following is an example of a sequence that might be used in a for statement? A. An integer B. A floating point number C. A list D. A boolean variable How is a…

Problem Statement: The mathematician Conway imagined a game, called game of life, which considered cells that are susceptible to reproduce, disappear, or survive when they obey certain rules. These cells are represented by elements on a grid of squares, where a grid has an arbitrary size. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squares that contain other cells. The rules are stated as follows: 1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation. Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation. Write a program that simulates this game and displays all successive…

You will be expected to isolate both the product id number and company number from the barcode number of the item to be purchased by the customer. Input You will receive (from the user) the following as input (in order): • The first and last name of the customer (e.g., Eric Poitras) • The item to be purchased, identified through a barcode number (e.g., 1909238092) • The cost of the item to be purchased by the customer (e.g., 8.50) • The cash amount given by the customer (e.g., 10.00) Processing 1. Extract the product id and company id numbers 2. Print the data stored in each variable in the corresponding format Output 1. Customer (Last, First): {LAST} {FIRST} 2. Item Number (Product, Company): {PRODUCT} {COMPANY} 3. Item Cost: (COST} 4. Cast Amount: {CASH} Examples Input Output Eric…
Assignment Java: Program Statement: You are required to model a vehicle parking lot system. The parking lot has a facility to park cars and scooters. The parking lot contains four parking lanes-two for cars and two for scooters. Each lane can hold ten vehicles. There is an operator with a console at the East end of the parking lot. The system should be able to handle following scenarios. Arrival of a vehicle: Type of vehicle (car or scooter) and Registration No. of vehicle should be entered Program should display suitable parking slot Vehicles arrive at East end, leave from West end Departure of Car: If not western most, all cars should be moved to the west When the car is driven out, rest of the cars should be moved to the left Vehicle data should be updated Departure of Scooter: Scooters should be able to drive out at random Vehicle data should be updated Note that when desired the operator must be able to obtain information like number of vehicles, number of scooters or number…
